The FM27C040 is a high performance, 4,194,304-bit Electrically Programmable UV Erasable Read Only Memory. It is organized as 512K words of 8 bits each. Its pin-compatibility with byte-wide JEDEC EPROMs enables upgrades through 8 Mbit EPROMs. The "Don't Care" feature on VPP during read operations allows memory expansions from 1M to 8 Mbits with no printed circuit board changes.

The FM27C040 provides microprocessor-based systems extensive storage capacity for large portions of operating system and application software. Its 120ns access time provides high speed operation with high-performance CPUs. The FM27C040 offers a single chip solution for the code storage requirements of 100% firmware-based equipment. Frequently used software routines are quickly executed from EPROM storage, greatly enhancing system utility.

The FM27C040 is manufactured using Fairchild's advanced CMOS AMG™ EPROM technology.
